Siren Affiliate Manager is an exceptionally well-designed and thoughtfully built WordPress plugin. If you're running an affiliate program with multiple affiliates, different transaction types, or custom engagement triggers that need to generate commissions, this tool gives you serious power and flexibility. What really sets it apart, though, is the developer. Alex has been incredibly helpful and willing to customize the plugin for my specific use case. More importantly, he was focused on creating real value for my business - not just billing hours. That kind of mindset is rare. The plugin is robust, flexible, and clearly built by someone who understands real-world affiliate program complexity. I can't recommend Siren highly enough.

What This Recipe Does

This recipe creates a single program that rewards customers with a flat $5.00 of store credit every time they make a purchase. Unlike a referral-based affiliate program, this one uses manual attribution. You enroll customers as collaborators and they earn rewards on their own purchases.

The reward is paid in store credit, a custom currency the customer spends on a future order, rather than a cash payout. This is a loyalty and retention play, not a referral play. Choose this recipe when you want to reward customers for buying, not for promoting.

Who It’s For

Store owners who want to incentivize repeat purchases without asking customers to share links
Subscription businesses looking to reward customers for renewals
Anyone building a loyalty program as a complement to or alternative to a traditional affiliate program

How It Works

Your customers earn store credit just by shopping with you. You add each customer to the program as a collaborator, and when they make a purchase, you or an automation attributes the transaction to them. They earn a flat $5.00 credit per order, regardless of how much they spent.

This approach works well for stores that want to build loyalty without the complexity of referral tracking. There are no links to share, no codes to remember. Customers just buy and earn. The reward amount is the same whether someone places a $20 order or a $200 order, which keeps the program easy to understand and communicate.

Attribution uses a “newest engagement wins” model, but since each customer’s engagement is unique to them, this effectively means each customer earns independently on their own purchases.

Automating store credit at checkout

The reward is paid in a custom store-credit currency rather than cash, so it stays inside your store and pulls customers back for another order. Defining that currency and rewarding customers in it are free-tier features, and on the free tier you issue each balance by hand.

To make it automatic, add a credit autofulfiller. It turns each earned balance into a coupon that applies at the customer’s next checkout, so the credit redeems itself with no manual step. The binding is a Siren Essentials feature, which keeps the program free to run and makes the automation the upgrade. Add it by binding the store-credit currency to the built-in credit fulfillment method:

{
  "autofulfillers": {
    "storeCreditAuto": { "currency": "STORE_CREDIT", "method": "credit" }
  }
}

How the Customer Rewards Program Works in Siren

1

Start with a ready-made program

The recipe sets up one loyalty program: a $5.00 credit per purchase, paid in USD, with manual attribution already wired in. You adjust the credit amount, not the structure.
2

Define partners and eligibility

Enrollment is the gate. Add customers as collaborators through the Siren admin or a registration form, and only enrolled customers earn the credit. The reward goes to people who already buy from you, not to outside promoters.
3

Set tracking rules

There are no links or codes. Each purchase is attributed to the customer who placed it, by hand or through an automation, and because every customer's engagement is unique to them, each one earns independently on their own orders.
4

Customize rewards

Every order earns the same flat credit whether it totals $20 or $200, so the whole offer fits in one sentence on a product page. Raise the default $5.00 if your margins support a bigger thank-you.
5

Manage approvals and payouts

Review attributed purchases before any credit is issued, then approve and pay inside Siren. Clear them as each order comes in or in periodic batches, whichever rhythm fits how you run the store.

Why Use Siren for a Customer Rewards Program?

Traditional customer loyalty software tools	Siren
Built for one program type	Built for multiple incentive programs
Often limited to one reward model	Supports commissions, bounties, royalties, revenue share, and bonuses
Rewards usually tied to one action	Rewards can be tied to different measurable actions
Harder to manage overlapping programs	Program groups and rules control how programs interact
May require multiple tools as you grow	Supports different partner programs from one system

Dedicated customer loyalty software usually stops at points and perks for shoppers. Siren treats loyalty as one incentive program among many, so the same install that credits repeat buyers can later run referral, affiliate, or milestone programs alongside it.

Connect Your Customer Rewards Program to the Tools You Already Use

Siren works as the incentive layer behind the systems where partner-driven actions happen: your website, checkout, ecommerce store, forms, LMS platform, subscription flow, or custom workflow.

Frequently Asked Questions

What is a customer rewards program?

A customer rewards program gives your existing customers something back for continuing to buy from you. In this recipe, that's a flat $5.00 credit on every purchase they make. It's a retention tool rather than an acquisition one: you're thanking people for coming back, not paying outsiders to send you traffic.

How does a customer rewards program work?

You enroll customers in the program, and from then on each purchase they make earns a defined reward. There are no referral links here: a purchase gets attributed to the customer who placed it, either manually or through an automation, and Siren records the $5.00 credit. Order size doesn't change the reward, so customers always know exactly what they'll get back.

Why is the incentive amount 500 instead of 5 in the JSON?

The amount is stored in the currency's smallest unit. Store credit is valued one to one with your store currency, so 500 means $5.00 of credit. When adjusting the reward, use that smallest unit (for example, 1000 for $10.00 of credit).

Does this require a specific Siren plan?

No, not to start. The store-credit currency and rewarding customers in it are free-tier features, and you can issue each balance by hand. Automating it, so the credit becomes a coupon that applies at the customer's next checkout, uses a credit autofulfiller, which is a Siren Essentials feature.

Do customers need to share referral links?

No. Customers earn rewards on their own purchases. There are no referral links involved. Attribution is handled manually or through automation.

Can I run this alongside an affiliate program?

Yes, and many stores do. Your customers earn rewards on their purchases while your affiliates earn commissions on referred sales. The two programs operate independently.

How do I enroll customers in the program?

Add them as collaborators, either manually through the Siren admin or through a registration form. Once enrolled, they earn rewards on every purchase.
